Abstract: A shroud of a vane of a turbine is provided. The shroud includes a shroud main body comprising a first wall having a gas-passage face facing a hot gas passage of the turbine and a cooling face facing opposite to the hot gas passage, a shroud edge disposed on a circumference of the shroud main body to surround the shroud main body, the shroud edge comprising a shroud edge passage therein, and an impingement box disposed to face the cooling face of the first wall so as to be spaced apart from the cooling face of the first wall. The impingement box comprises a cooling air inlet to introduce a cooling air from the shroud edge passage into an inside of the impingement box, and an impingement air hole configured to jet the introduced cooling air to the cooling face of the first wall to cool the cooling face of the first wall.

Abstract: A carbon material for a non-aqueous secondary battery containing a graphite capable of occluding and releasing lithium ions, and having a cumulative pore volume at pore diameters in a range of 0.01 ?m to 1 ?m of 0.08 mL/g or more, a roundness, as determined by flow-type particle image analysis, of 0.88 or greater, and a pore diameter to particle diameter ratio (PD/d50 (%)) of 1.8 or less, the ratio being given by equation (1A): PD/d50 (%)=mode pore diameter (PD) in a pore diameter range of 0.01 ?m to 1 ?m in a pore distribution determined by mercury intrusion/volume-based average particle diameter (d50)×100 is provided.

Abstract: A differential output circuit is controlled according to its mode of operation. While in the first mode, the differential output circuit controls a current flow through a variable current source according to an impedance of the variable current source, and while in the second mode, the differential output circuit compares a voltage at a monitored node and a reference voltage and controls the current flow through the variable current source to make the voltage at the monitored node to be equal to the reference voltage.

Abstract: Provided is a test apparatus having a bad block memory for storing a plurality of pieces of fail information in association with blocks of a memory under test, each piece of fail information indicating whether there is a defect in the associated block. The test apparatus writes a test data sequence to a page under test of the memory under test, reads the test data sequence written to the page under test, and compares the read data sequence to the written data sequence. The test apparatus includes an allocation register that stores allocation information for setting which of the plurality of fail conditions for judging whether there is a defect in the page under test are allocated to the plurality of pieces of fail information.
